摘要
长基线高精度GPS网解算是一项较复杂的数据处理工作,用户静态GPS观测数据与连续运行参考站(continuously operating reference stations, CORS)的基准站数据组网解算具有一定优势,但基准站坐标属于保密数据,普通测绘用户不易获取。为解决该问题,采用网络计算模式来实现CORS-GPS组网解算。基于UNIX平台及GAMIT/GLOBK解算模块,采用Socket多线程并发通信技术,研制了服务器端软件;基于Windows系统研制了客户端软件,解算过程由用户发送数据到服务器自动解算,将解算结果反馈给用户。实验结果表明,技术路线可行可靠,为CORS-GPS组网解算提供了技术模式,拓展了CORS系统高精度定位服务。
It is a complex technical work to solve long baseline GPS network with high precision. There are some advantages to combine the static GPS observation data of users with that of CORS reference stations. The reference stations coordinate’s data are usually confidential, which cannot be obtained easily by ordinary users. Based on UNIX operation system and GAMIT/GLOBK software, a server software is developed by using the socket multithread concurrent communication technology and the corresponding client software is developed in Windows OS. The CORS-GPS network solution is solved by using network computing mode. The calculation process consist of sending data to the server by the user, automatic calculation by the server, finally, and the feedback of calculation results to the user. The experimental results show that the method is feasible and reliable. It provides a new technical mode for high precision CORS-GPS network adjusting, and can provide high precision positioning services for CORS center.
